Abstract

Embodiments of the disclosure disclose a display panel, a method for displaying an image on the same and a display device. For the determined brightness mode, every n frames of images to be displayed are taken as a group, and when being displayed, each group of n frames of images is controlled to emit light for the same total amount of time; and when each frame of image is being displayed each row of pixels operate in the light-emitting phase for the same amount of time, so that the images can be displayed with normal brightness in this mode. When n frames of images in a group are being displayed, different light-emitting control signals are transmitted to the same row of pixels. And/or, when each frame of image in a group is being displayed, at least two of light-emitting control signals transmitted to different rows of pixels are different.

Claims (40)

1. A display device, comprising a display panel displaying an image on the display panel using a method comprising:

for a brightness mode:

displaying a plurality of groups of n frames each, wherein every group has a same total light-emitting time, wherein a total light-emitting time of each group equals to a sum of light emitting time of all n frames, wherein n is an integer greater than 1;

wherein when displaying each frame of image, transmitting a light-emitting control signal having at least one pulse cycle to each row of pixels in the display panel, wherein the pulse cycle comprises a light-emitting phase and a closing phase, each row of pixels operate in the light-emitting phase for a same amount of time, and wherein a frame of image emits light when a row of pixels operate in the light-emitting phase in within one frame;

wherein when n frames of images in a group are displayed, at least two of light-emitting control signals transmitted to a same row of pixels are different.

2. The display device according to claim 1 , wherein the display panel comprises two light-emitting control circuits; and

one of the light-emitting control circuits is configured to provide odd rows of pixels with a light-emitting control signal, and the other light-emitting control circuit is configured to provide even rows of pixels with a light-emitting control signal.

3. A display panel, displaying an image on the display panel using a method comprising:

for a brightness mode:

displaying a plurality of groups of n frames each, wherein every group has a same total light-emitting time, wherein a total light-emitting time of each group equals to a sum of light emitting time of all n frames, wherein n is an integer greater than 1;

wherein when displaying each frame of image, transmitting a light-emitting control signal having at least one pulse cycle to each row of pixels in the display panel, wherein the pulse cycle comprises a light-emitting phase and a closing phase, each row of pixels operate in the light-emitting phase for a same amount of time, and wherein a frame;

wherein when n frames of images in a group are displayed, at least two of light-emitting control signals transmitted to a same row of pixels are different.

4. The display panel according to claim 3 , wherein the display panel comprises two light-emitting control circuits; and

wherein one of the light-emitting control circuits is configured to provide odd rows of pixels with a light-emitting control signal, and wherein the other light-emitting control circuit is configured to provide even rows of pixels with a light-emitting control signal.

5. A method for displaying an image on a display panel, comprising:

for a brightness mode:

displaying a plurality of groups of n frames each, wherein every group has a same total light-emitting time, wherein a total light-emitting time of each group equals to a sum of light emitting time of all n frames, wherein n is an integer greater than 1;

wherein when displaying each frame of image, transmitting a light-emitting control signal having at least one pulse cycle to each row of pixels in the display panel, wherein the pulse cycle comprises a light-emitting phase and a closing phase, each row of pixels operate in the light-emitting phase for a same amount of time, and wherein a frame of image emits light when a row of pixels operate in the light-emitting phase in within one frame;

wherein when n frames of images in a group are displayed, at least two of light-emitting control signals transmitted to a same row of pixels are different.

6. The method according to claim 5 , wherein when one frame of image in a group is displayed, at least two of light-emitting control signals transmitted to two rows of pixels are different.

7. The method according to claim 5 , wherein when different frames of images in a same group are displayed, light-emitting control signals transmitted to a same row of pixels are in the light-emitting phase for a same amount of time; and

wherein when each frame of image in a group is displayed, at least two of light-emitting control signals transmitted to different rows of pixels are different.

8. The method according to claim 7 , further comprising wherein when any two adjacent frames of images in a same group are displayed, light-emitting control signals transmitted to a same row of pixels comprise different numbers of pulse cycles, wherein each of the pulse cycles has a same duty cycle; and

wherein when each frame of image in a group is displayed, at least two of light-emitting control signals transmitted to different rows of pixels are different.

9. The method according to claim 6 , further comprising:

at least two light-emitting control signals transmitted to the two rows of pixels have different numbers of pulse cycles.

10. The method according to claim 9 , further comprising transmitting light-emitting control signals having a same number of pulse cycles to all odd rows of pixels and transmitting light-emitting control signals having a same number of pulse cycles to all even rows of pixels; and wherein:

the number of pulse cycles in one of the light-emitting control signals transmitted to all the odd rows of pixels is different from the number of pulse cycles in one of the light-emitting control signals transmitted to all the even rows of pixels.

11. The method according to claim 5 , wherein when different frames of images in a same group are displayed, light-emitting control signals transmitted to a same row of pixels are in the light-emitting phase for a same amount of time;

wherein a light-emitting control signal transmitted to a row of pixels for displaying at least one of any two adjacent frames of images in a same group has at least two pulse cycles and at least two duty cycles of the pulse cycles are different.

12. The method according to claim 11 , wherein when any two adjacent frames of images in a same group are displayed, light-emitting control signals comprising a same number of pulse cycles are transmitted to a same row of pixels.

13. The method according to claim 5 , wherein when different frames of images in a same group are displayed, light-emitting control signals transmitted to a same row of pixels are in the light-emitting phase for different amounts of time.
